To all :whom "it mayconcerm' l Be 1t known that-I, EDWIN S. Woons, a

' citizen of the'United States, and a resident erence marked thereon, which forma. partv of Chic'ago,in the county of Cook and State [of Illinois, have inventedv certain new and useful- Improvements in- Antifriction-Bearings and I do hereby declare thatvthefollowing is a full,I clean-.and exact'description thereof, reference being had tothe accompanying drawings, and to the letters of refof this specification.

This linvention relates to l improvements infan antifriction bearing and is shownas l,for railway. cars.-

embodied'in anantifriction center bearing f Certain features lof.. the; linvention are adapted. to other and. more general uses.`

The invention consists in the'matters herepointed out in the appended' claims.

4inafter set forth and more particularly.

. Amongthe objects ofthe invention-is to l jv assemblage ofthe bearing in-a caror other 'place o'f use and lts removal therefrom.

improve andxsimplifythe construction of- .bearings of the type herein.'l shown and to provide a construction which facilitates `the Other objects of the inventionwill appear from the following ldescription.-

In' the drawings :-Figure 1 is an axial vertical sect-ion of a centerbearing made. in accorclance-with my invention, taken on line 1- 1 of F ig. 2.' F ig. l2 is a bottom plan view of the upper bearing` member and the antifriction elements supported therein. Fig. 3 is.

an endview of one-of the antifrictionele'- ments.` Fig. 4. 1s a' fragmentaryview of 1a' thrust ring constituting part of lthe bearing.

'I lowersides with annular, inwardly inclined bearing surfaces on the adj acent'sides of the bearing members. The inc llned bearmg surfaces of said upper and lower membersare `formed on annular, radially inclined wearA plates 14, 15, respectively, which are attachedto said bearing members by rivets or the like. -The upper bearing member is prof vided centrally with a hub portion 16' wh ich extends downwardly into a, central opening. 17of the lower member, said hub being designed to receive the king'pinof the bolsterand itself having bearing in the lower meinber.

' The anti'friction elements 'herein shown 60 are made like those illustrated in my prior application for U. S. .Letters Patent No.

- 391,039, and September, 3rd, 1907,.in that their adjacent. sides are flattened or cut away, and they are nested closely together 65 in the annular space or chamber between the upper and lowerbearing membersto provide a maximum linear-contact between the bear ing members and antifriction elements, The

particular form yof antifriction. element shown lcomprises upper and lower bearing arcs 20, 2 1 adapted .for contact with the wear plates of the upper and lower members, re-

spectively, and llattened sides which are formed withtransvers'ely ourvedlateral suri '(5 -faces 22,22 and intermediate concave sur- Qfaces '23; the convex surfaces of'each antifriction element being adaptedto engagecorresponding convexsurfaces 'of a contigo; ous antifriction' elementfto admit'of close 80 spacing of said antifriction elementag' Thesaid concave and convex are arranged. to afford. stops, when the -nliifricl tion elementsA assume their, greatestincline-- tion vfrom -`their normal olioentra rp'sitioixe, .-85
